Fig 4. a-d: Bar graphs with element weight fractions within neutrophil nuclei (left column, Fig 4a-b) and cytoplasms (right column, Fig 4c-d) throughout PMA stimulation for P, S, K, Cl, K, Ca, Mn, Fe, Co (upper row) and for Ni, Cu, Zn, Se, Br, Sr and Pb (lower row).

Fig 4

Neutrophils from control culture are indicated in green, 1 h PMA-stimulated neutrophils in blue and 2 h PMA-stimulated neutrophils in red. Weight fractions are expressed in %, ppm or ppb in a (different) logarithmic scale. Weight fraction values are normalized to the Compton intensity of neutrophil “0h_donorA_ cell1”. Error bars are based upon Poisson counting statistics and the certified uncertainty values of NIST SRM1577C “Bovine liver”.
